摘要
A Raman analyzer for analyzing light emitted from a Raman cell is provided that has a beam splitter configured to split the light emitted from the Raman cell into a first beam and a second beam. An atomic vapor filter can be used to filter a Raman scattered line from the first beam and a chopper system can periodically interrupt the first and second beams that are directed towards a photo detector which can convert light from the first and second beams into an electrical signal. The signal output from the photo detector can optionally be amplified digitized Fourier filtered and/or subjected to Fourier analysis.
